Book recommendation:

Glasshouse

On the face of it, this appears to be another post-Singularity romp in a post-scarcity society. It is, but it's also a damning critique of gamification. Imagine the Stanford prison experiment if it were run by godlike experimenters. Stross's Accelerando remains the definitive description of an unfolding Singularity, but Glasshouse is the one that has stayed with me.
